Social Bookmarking is the Rage.

The primary use of bookmarking is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere.
Many bookmarking sites are available which offer many other stuff such as web hosting.
Some of them are:
Add-ons are available for your browser (IE and Firefox) in case of most of the bookmarkong sites.
My favourite is Delicious , the reason being its simple interface 
and add-on support in firefox.
Some Survey has Ranked Digg,Reddit and Delicious as 1st, 2nd , 3rd in social bookmarking.
Del.icio.us describes itself as follows.
“del.icio.us is a collection of favorites – yours and everyone else’s. You can use del.icio.us to:
- Keep links to your favorite articles, blogs, music, reviews, recipes, and more, and access them from any computer on the web.
- Share favorites with friends, family, coworkers, and the del.icio.us community.
- Discover new things. Everything on del.icio.us is someone’s favorite — they’ve already done the work of finding it. So del.icio.us is full of bookmarks about technology, entertainment, useful information, and more. Explore and enjoy.
del.icio.us is a social bookmarking website — the primary use of del.icio.us is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere, too. On del.icio.us, you can use tags to organize and remember your bookmarks, which is a much more flexible system than folders.
You can also use del.icio.us to see the interesting links that your friends and other people bookmark, and share links with them in return. You can even browse and search del.icio.us to discover the cool and useful bookmarks that everyone else has saved — which is made easy with tags.
All you need is a browser and an internet connection.”
